How to Prepare Your Philadelphia Home for Storm Season 2025
Nor'easters, tropical remnants, and severe thunderstorms all threaten Philadelphia-area homes. This complete storm preparation guide from Bulldog Restoration helps you protect your property before the next storm hits.
Philadelphia's Storm Season: What Homeowners Face
Greater Philadelphia sits in one of the most storm-active corridors in the eastern United States. Nor'easters can dump 18 inches of snow followed by rain, causing roof collapses and basement flooding. Tropical storm remnants (like Ida in 2021, which caused catastrophic flooding across Bucks and Montgomery counties) can drop 6–8 inches of rain in hours. Summer severe thunderstorms routinely produce wind gusts exceeding 60 mph, taking down trees and damaging roofs across the region.
The good news: most storm damage is preventable with the right preparation. This guide from our storm damage restoration team walks through everything Philadelphia-area homeowners should do before storm season — and what to do when a storm hits.
Spring Pre-Storm Preparation (March–April)
Roof Inspection Checklist
Your roof is your home's first and most critical line of defense against storm damage. After winter, inspect for:
- Missing, cracked, curling, or loose shingles — even a few damaged shingles can allow significant water intrusion during heavy rain
- Damaged or missing flashing around chimneys, skylights, vents, and wall junctions — the most common source of roof leaks
- Sagging or soft areas in the roof deck — may indicate rotted sheathing from prior water intrusion
- Granule loss in gutters — indicates shingle age and declining water resistance
If you're not comfortable on a roof, hire a licensed roofing contractor for a spring inspection. Addressing small issues in spring is dramatically less expensive than emergency storm damage restoration after a major storm.
Gutter and Downspout Maintenance
Clogged gutters overflow during heavy rain, directing water against your foundation and fascia boards. Clean gutters of all debris after winter and again in late fall. Ensure:
- Downspouts discharge at least 4–6 feet from your foundation
- Downspout extensions are installed where needed
- Gutters are pitched toward downspouts (no standing water after rain)
- All seams and end caps are watertight
Basement Waterproofing and Sump Pump Maintenance
Philadelphia's clay-heavy soils expand when wet, creating hydrostatic pressure against basement walls. Combined with the region's high groundwater table in many Bucks and Montgomery County communities, basement flooding is one of the most common water damage restoration calls we receive — and one of the most preventable.
Test Your Sump Pump Before Storm Season
Pour water into the sump pit to confirm the pump activates at the correct water level and discharges effectively. Check the discharge pipe for obstructions or freeze damage. Install a battery backup sump pump — power outages during severe storms are common, and a failed sump pump during a power outage can lead to thousands of dollars in basement flooding damage.
Seal Foundation Cracks
Any visible crack in your basement walls or floor should be evaluated and sealed before storm season. Hydraulic cement can address minor seepage cracks. Larger cracks or horizontal cracks (which indicate structural pressure) require professional assessment.
Tree and Landscape Preparation
Falling trees and large limbs are responsible for a significant portion of storm damage across the Philadelphia region. Every spring:
- Have large trees within fall distance of your home assessed by a certified arborist for structural integrity, disease, and dead branches
- Remove dead or dying trees proactively — a dead tree in a windstorm is a guided missile
- Trim all branches within 6 feet of rooflines, gutters, or power lines
- Identify trees with significant lean or shallow root systems — these are highest-risk in wind events
Building Your Emergency Kit
Pennsylvania Emergency Management recommends every household maintain a minimum 72-hour emergency kit. For storm preparedness, include:
- One gallon of water per person per day (3-day minimum, 7-day recommended)
- Non-perishable food for 3–7 days
- Battery-powered or hand-crank radio
- Flashlights and extra batteries (or rechargeable flashlights)
- First aid kit and a 7-day supply of any prescription medications
- Copies of important documents (insurance policies, IDs, medical records) in a waterproof bag
- Phone charger power bank — charge it monthly
- Cash in small bills (ATMs may be offline after major storms)
Know Your Flood Zone
FEMA maintains Flood Insurance Rate Maps (FIRMs) for all of Pennsylvania. Homeowners in Special Flood Hazard Areas (Zones A and V) face significant flood risk and are typically required by lenders to carry flood insurance if they have a federally-backed mortgage.
But even homeowners outside mapped flood zones should understand their risk. Approximately 25% of flood claims in the U.S. come from properties outside high-risk flood zones. Check your property's flood zone at FEMA's Map Service Center. If you're in or near a flood zone, consider purchasing flood insurance through the NFIP or a private carrier — standard homeowners policies do not cover rising water flooding.
What to Do When a Storm Hits
During the Storm
Stay indoors and away from windows. Monitor emergency alerts via NOAA Weather Radio or your smartphone's emergency alerts. If flooding begins, move to upper floors — never try to walk through moving flood water. Do not use electrical outlets or appliances in areas that have gotten wet.
Immediately After the Storm
Once it's safe to go outside, document your property from the outside before entering. Look for:
- Damage to your roof (missing shingles, damaged flashing, debris impacts)
- Downed trees or limbs near the structure
- Foundation cracks or soil displacement
- Water in the basement or crawl space
Photograph everything before any cleanup or repair begins. Call your insurance company. And if you have structural damage, flooding, or downed trees on your home, call Bulldog Cleaning & Restoration at (267) 982-5504 for 24/7 emergency response.
